below is a thread I posted on the Patrol list and thought i'd see what info I could pick up here aswell

I am currently looking to trade in my Hilux on either a N/A or a TD
4.2 GU Patrol. As there is a chance I may be purchasing at auction,
what things should I be looking for fault wise.

I do realise these are a very tough truck and it takes a bit to hurt them, but I don't wanna fork out the mulah to find I have to fork out a fair whack more.

Any comments/suggestions would be appreciated.

cheers,
Sam.

Ex Gov? Private?

IMHO.

Ex Gov: Some are serviced meticuliously, others are driven to the ground. All care no responsibility useage.. Mate made $8k on an ex auction one

Private: things usually worth nothing or bent or broken go to car auction, wouldnt buy private from auction.

You never know what your getting at Auction..

Be careful.. You would want to be saving a lot of Moula to buy at Auction..

My way of thinking is if its a turbo it should have a timer, if not then they may or may not of taken care of the engine.
Thats just one non-test driven indication i would look at.

(i know about the legal issue)

maybe should look into modern turbo systems as well! turbo timers or turbo savers do stuff all as far as protecting an engine but to be fair they dont hurt anything either

Sam, the big unknown that you will be up against is the problem with 5th gear on the 4.2 and early 3 litre models. You would need to see some written evidence that the factory modification has been done to the car or else you will be the bunny wearing the $2000 repair bill when and I mean WHEN the mainshaft and fifth gear decide to seperate. This is a huge problem awaiting to bite many second owners on the arse when they discover that the first owners has not had the fault rectified under warranty. As the fault was not subjected to a general recall, some cars may still be out there as time bombs waiting to go off.

That applies for vehicles from 2000 (series II) to 2002.

Gearboxes were revised then and the fault introduced.

THere was a fault in manufacturing tolerances....

Guys,

I own a Feb 2002 Model, but it was built oct 2001. Is this before the bad batch. I have just ticked over 100 000km and (Touch Wood) have had no problem with the Gearbox and alot of the time towing a 2500kg boat including 1 trip in 5th gear most of the way from Brisbane to Adelaide. Only problems i have had is the roof cracking from the upright supports and the rear left hand wheel shearing the studs clean off at 100km/h whilst on the Newel Hwy but thats another story.

I think GUPATROL means it was FIXED in the 2002 model, not INTRODUCED!!


then again, its not in them all, as GOona says, theres heaps of GU's with 100-200,000klms no problems.


Do tell about the wheel studs!!! And the Roof, someone was asking on the patrol list the other week about this, his ARB roofrack was the cause.... ???

Gee Goona,
you say the ONLY probs you have had with your 2002 model is "the roof cracking from the upright supports" and "the rear left hand wheel shearing the studs clean off at 100km/h" well i guess thats nothing too serious now, i think not. What response did you get from the dealer?
Cheers Peter

Sorry guys a bit of miss information. My truck is actually a 2000 model built in oct 1999. Hopefully this has missed the new "upgraded Gearbox".

Fellows, I have the 2000 3lt TD Patrol. Just fininished reading all your comments and now you've got me a little worried (buggars). At the moment I don't think I have any problems, have only done 65000 km. But are there any signs I should be listening to in fifth gear or does it just happen in an instant and without warning.

Mine failed at 65000kms. No towing, No stress in 5th, failed at 80km/h on a flat section of the Nullabor. The only clues are a slight resistance to moving the gearlever out of 5th. If you detect that you have to give it a slight tug, then you are on the way to a breakdown.
I also detected a slight driveline vibration when on light throttle at 60 km/h, say when slowing down through a town. Like a vibration you get when a uni joint is not right. These are very small, hard to pick symptoms, and may not reveal with every truck. Nissan will not look at it before it fails, so you are caught between that famous rock and that hard place. It has to break before they will believe you!!!

Back the truck up a bit fellas. The point I was trying to make is: there is/was a problem with 5th gear in GU's and the factory fixed the production line at October 2002. BUT, an owner whom only drives the kids to school, or only drives around a city, whom never really gets into fifth for any length of time, will not realise the problem. IT IS THE SUBSEQUENT OWNER, whom may like to tow or do long distance touring who will wear the failure. Unless the repair is documented by the previous owner, YOU MAY NOT KNOW IF THE GEARBOX HAS BEEN FIXED.

OK this is first hand info from Nissan to a friend of mine and I.

The problem was introduced in 2000 as gearboxes were revised Truckster.... Nissan revised the gearboxes when they introduced the 3.0L model.
On that revision, the people who manufacture the gears for Nissan stuffed up on the tolerances, not all vehicles were affected, the problem was resolved by 2002.
3.0L ones were more affected only because they have lower diff ratios and owners select 5th earlier.
This friend of mine did not tow and had a 4.2 but admitted that remained in 5th below 80kms/h. His Patrol was used normally, was not a city vehicle nor 100% highway.
Series1 Patrols should not be affected and series 3 patrols should not be affected.
Off course with any gearbox, do not "torque" the gearbox in fifth as that gear is not strong and that is common on all motor vehicles.
By design 5th gear is not part of the main set, sits on one side and has very small gears/teeth to keep it quiet at high speeds.
As a rule change to 4th while up hill below 80kms/h.

Thanks for that info desert. I haven't noticed any of those signs you mentioned as yet, but will be on the look out for them. Just read will's follow up about the series II having the major problem and that is the one I have, so even more worried now. If it is going to go, I hop it happens before September, that's when my factory warranty runs out.
